The chairman and a vice president of Samsung electronics are starting 18 months' prison sentences after being found guilty of illegal union busting yesterday at the Seoul Central District Court.

Chairman Lee Sang-hoon and executive vice president Kang Kyung-hoon were in charge of a wide ranging scheme to stop staff joining unions. This included cutting wages for staff who joined unions and probing workers' private lives. Some two dozen other Samsung executives were found guilty of related offences.
